Plots of slope of linear trends
X axis: Slope of time trend (i.e., change per year), wet-weight concentration
Y axis: Slope of time trend (i.e., change per year), wet-weight concentration
- Red line: Regression line (red) calculated using Deming (orthogonal) regression
- Blue dotted line: 1:1 line (same trend using w.w. and d.w. concentration)
